To all whom, it mayconcernf Be it known that I, CARL EIOKEMEYER, a citizen of the United States,residing in'Yonkers, in the county of Westchester and State useful Improvements in Machines for ,Blocking and'S aping Hats, of which the following is a specification.

This invention relates to improvements in United States Letters Patent N 0. 540,219,

Machines of this construction operated to better lay the felt on the block and more 0 chines, however,the-brim of the hat was simmeans were provided whereby the brim with the blocking of the crown'or at any time before the removalof the hat-body from the machine. Such operation was a subsequent one performed, by other devices after removal and banding machine. j V d i The present invention relates to means for stretching the brim and taking out. all un evenness in the felt between the band and the centered and properly clampedthroughout the blocking operation on a machine-ofthe type mentioned.

stretching-lever connected with said sup porting-ring and with" said stretching-ring,

and means for locking said stretching-ring to F the supporting-ring; and the invention consists, further, in certain details of construction. 'j and combinations of parts which will be fully and finally'pointed out described hereinafter evation, with parts removed, of a machine embodying my inventlon. Fig; 2'is a vertical section on the same scale as Fig. 1. j Fig. 3is a vertical transs Yersesection, ona larger scale, of a portion of the machine, showing in detail the brimclamping devices. Fig. 4 is a plan view of'ai portion of'the clamping jaw, supportin 1 ring, and connected parts. .Figy5 is a si e elevation of a lever mechanism for operating the clamping-jaws for stretching the hatbrim. Figs, 6 and? are respectively a front" elevation and a side elevation of a lever mechanism for. operating the clamping-jaws for clamping the hat-brim; Figs. 8 and 9-are I respectively a rear elevation, on an enlarged scale, and a side elevation of the clamping aws; and Fig. 10 is a rear elevation of a modified form of the same.

Similar characters of reference indicate corresponding parts.

Referring to'the drawings, a indicates the hat-block; Said block is secured to a suitable rest 2, mounted on a central spindle 3,

adapted to movevertically in-a suitable bear ing in the trough 6 of the machine, which extends between the side frame 7 andS; The block-support2 is provided witha flange 11,. adapted to engage-with ashoulder 12 of'a' main supporting-ring 13 16. Said main supporting-ring13 is provided at its upper por 15, which connect the inner portion 0 said ring with an outer rim portion 1 6 of the same.

mo .tionwith openings 14 andwith radiating-ribs r The inner portion'of the ring is provided with a laterally-extending flange 17, on which are supported, bysuitable bolts, brackets 18. To

said brackets are pivoted, by means of suit able fulcrum-pins 20, bell-crank clampingjaws 21. Each lever is provided at its upper end with a vertically-slotted projection 22, in which is guided the upper clamping-jaw 23. The lower arms of the lower clampinglevers 21 extend outwardly from the center of the machine instead of toward the center, whereby the use of a larger stretching ring 26 with increased wearing-space for the bosses 24 at the outer ends of said lower arms is obtained and the use of larger bosses permitted. The stretching-ringu26 is provided with lugs 27 28, one at the front and one at the rear of the machine, whereby said stretching-ring is guided on vertical guide-rods 29 and 30, respectively, carried by the main supporting-ring. Each jaw 21 carries at its upper portion a rest 31 for the hat -brim. Each jaw 23 is forked at its lower end, as indicated at 32, Figs. 8, 9, and 10, so as to avoid interference with the lower portion of the jaw 21, and is pivoted to a suitable standard 34, secured by a bolt 35 to a flange 36 of a clamping-ring 37. The standard 34 is secured yieldingly to the flange 36 by means of nut 38, between which and the flange 36 is located a yielding Washer e, of rubber or any other suitable elastic material.

The supporting-ring 13 16 is secured at its sides by means of suitable clamps 39 and 40 to sleeves 41 42, respectively, which slide on side rods 43 44, secured in position by any suitable means in the side frames of the machine. To the lower end of said sleeves are wrist-pins 52 54, to which are secured, respectively, suitable connecting-rods 100 101, whereby the supporting-ring and its connected parts are raised and lowered at the proper times.

A cross-head 55 is secured by any suitable means stationarily in position above the supporting-ring and clamping-jaws Said crosshead carries the banding shell 56, secured thereto by any suitable meanssuch, for instance, as those shown in the United States Letters Patent No. 540,219, previously referred to.

The clamping-ring 37 is secured by means of clamps 58 59 to sleeves 60 61, respectively, which sleeves are mounted to slide on the sleeves 41 42, respectively, of the supporting-ring. The stretching-ring 26 is secured by means of clamps 62 63 to sleeves 64 65, slidably mounted on the sleeves 60 61, respectively, of the stretching ring. To the stretching-ring are pivoted links 66 67, which are connected at their opposite ends to levers 69 7 0, respectively, fulcrumed at their rear ends to suitable brackets 74 75, depending from the supporting-ring 13 16. Each lever 69 is provided with a handle 76 and a spring-pawl 77, engaging a rack 80, secured to the rim 16 and to a bracket 81 of said rim.

To the clamping-ring 37 are pivoted links 84 85, the opposite lower ends of which are connected, respectively, with levers 88 89, which levers are fulcrumed at their rear ends by means of a rock-shaft 90, to which they are secured, to brackets 74 75, respectively, of the supporting-ring. To the rock-shaft 90 is fixed a forwardly-extendin g lever 93, which is provided at its forwardportion with a toggle-lever-locking mechanism comprising a crank 94, pivoted to said lever 93, and at its front to a link and having a handle. The link 95 is provided with a stop 96, adapted to abut against the crank 94. Said link is fulcrumed to a bracket 98, projecting from rim 16 of the supportingring.

The operation of the machine is as follows: The hat-body is placed in upright position, with the brim of the hat resting upon the faces 31 of the lower clampingjaws. The lever 93 is now depressed by means of the handle on link 95 into the position indicated in full lines in Fig. 7. By this operation the lever 93 operates through rock-shaft 90 and levers 88 89 and links 84 85 the clampingring 37 in downward direction, whereby the heads of the upper clamping-jaws 23 are depressed upon the hat-brim and the latter thereby clamped between said heads and the rests 31 of the lower clamping-jaws. The levers 69 70 are now depressed to the desired extent, whereby links 66 67 are moved in downward direction, drawing downwardly the stretching-ring 26. Thereby the clamping-jaws 21 23 are swung together outwardly upon their pivots, thereby stretching the brim. When the hand-levers 69 70 are drawn to the desired point, the pawl 77 is permitted to engage the rack, whereby the levers and the clamping-jaws are locked in the position to which they have been moved. The further operations of blocking take place in the sequence set forth in the patent hereinbefore referred to, No. 540,219. During the operation of blocking the brim-holding device described securely holds the brim, so that all unevenness of the felt is stretched out of the brim during the blocking process. The hat then receives a jet of water, which sets the stiffening. The operations of raising the brim-cla1nping device and hat-block a to the banding-shell and the admission of steam to the shell at the proper time for laying the crown upon the block may all be performed by devices similar in construction to those shown in the patent referred to, and need not be here specifically described. hen the banding and blocking of the hat, together with the stretching of the brim, have been accomplished, the levers 69, 70, and 93 are released, so that the clampingjaws may return to their original position, and the hat -block, with the handed and stretched hat thereon, is then removed and a fresh block placed in position within the supporting-ring.

I Having thus described my invention, I

claim as new and'desire to secure by Letters Patent ring, upper clamping-jaws pivoted to said clamping ring, a stretching ring slidably mounted on said clamping-ring and engaging said lower clamping-jaws, operating devices connected with said supporting-ring and clamping-ring for operating the latter relatively to the former for closing said clamp- 1ng'jaws, means for locking said operating devices to the supporting-ring, a stretchinglever connected with said supporting-ring and with said stretching-ring, and means for locking said stretching-ring to the supporting-ring.- 1 i 2.
